Trying to find out what sort of seating pressure Web Cams offer on their valvetrain upgrade for their Pro Series (with the extended rocker arms) but not much is revealed on their website. I'm planning a high boost (40psi+) build and was thinking of using the 85lbs Supertech option, but I'm afraid that this might be a bit too weak.

On the other hand, I see Ferrea offers a 110lbs option as does Supertech with a 100lbs which is all good and well but might be overkill.

 

have you tried calling web cams directly for information like this?

 

Its has a lot of lift, so make sure whatever you get you don't coil bind.

We run them in some of the heads and there are a couple different methods to get enough seat pressure, but also have room in the spring. I'd be happy to help over the phone 317-440-6777

 

Will contact them, just need to get the time zone dialling times right. Thanks for the offer 4piston.
